Quercitrin increases antioxidant enzyme expressions reduced by UVB exposure. A, B, and C, JB6 cells were pretreated with quercitrin (10, 20, and 40 μM) or aceton for 1 h followed by UVB exposure. A, The whole cell protein lysate were isolated for immunoblotting to examine the expression levels of catalase, SOD1, and SOD2. B, Mitochondrial protein were fractioned and subjected to immunoblotting to examine SOD2 expression level. C, The animal treatment is the same as Fig. 1. At 1 day and 7 days after 6-week UVB exposure, the mice dorsal skin tissues were isolated and homogenized for GSH/GSSG measurement.* indicates a significant difference compared with control without UVB exposure (p<0.05). # indicates a significant difference compared with 240 mJ/cm2 UVB exposure (p<0.05).
